Cummins 3907176 12v big bowl marine/pulling pistons

[Kustum_kid]

These pistons have the really low top ring placement, great for high boost! These also use a larger wrist pin also (I am including them). I would like to get 400 plus shipping. They are std size.

Terrible description what take a picture of the bowl and does it have rings

The pin for these marine pistons is longer than a regular one. So, you must have the correct pin to use them. I can take a picture of the difference if you guys would like to see. It would only let me add one picture. I took a picture of the part I felt was important, the top ring placement. Anyone wanting more pictures pm me your # and I can text them to you. The pistons do not come with rings, but they do come with new pins and clips. Rings I will throw in for a extra $100
